[Texture Parameters] Interface to actually cache Images in the Mutable system and make them availabe at run-time. Any cached image has to be registered by an Image provider before caching it. Have in mind that once an image has been cached, it will spend memory according to its size, except in the case of images of typeUCustomizableSystemImageProvider::ValueType::Unreal_Deferred, where only a very small amount of memory is used and the real texel data is loaded when needed during an update and then immediately discarded [Texture Parameters] Cache an image which has to have been previously registered by an Image provider with the parameter id.
